http://funnix.com/ Found this posted at a homeschooling sub-forum at another site I frequent. I signed up for it, and right after received an email with links to download both the Funnix Beginner and Funnix 2 programs, a serial# to register the programs, and links to the pdf versions of the textbooks and workbooks. eta: The files are really big, with a lot of stuff. They recommend at least 2gig of free space on your hard drive.
